THE DAY THE EPHEMERIS STOOD STILL —
again!
This time it was a catastrophic crash with no possibility of easy recovery.
Sources had to be ported to a new platform. The crash of course happened at
a very inopportune time, when I was not in a position to work on this site.
The good news is that this new host can be backed up automatically,
and the sources rebuilt in a way that will allow fast recovery on any
new host in the future. Thanks for hanging in there!

Positions are based on JPL's ephemerides. JPL makes no claim
as to the accuracy or suitability of their ephemerides for any purpose.
ephemeris.com is not associated with JPL, but does use their publicly
available ephemerides.

You can also consult the
JPL Horizons
Ephemeris Generator for positions of the planets, asteroids, and comets.
JPL's planet positions are derived from their DE405 ephemeris. The software
section of ephemeris.com contains a free software package to read, write, and
interpolate DE405 (the world's most accurate planetary database), and any other
JPL planetary ephemeris. The software is available under the Lesser Gnu Public
